Yes, I can reproduce it reliable. But I use 3-nodes ($redundance=3)

I can get it working by introducing a sleep(5) after auto_deploy:

    my ($rc, $res) = $hdl->create_resource($name, {});

    ($rc, $res) = $hdl->create_volume($name, $size, {});

    my $redundancy = get_redundancy($scfg);;
    ($rc, $res) = $hdl->auto_deploy($name, $redundancy, 0, 0);

    sleep(5); # else we get split brain?!
    ($rc, $res) = $hdl->set_drbdsetup_props(
	    target => "resource",
	    resource => $name,
	    type => 'neto',
	    'allow-two-primaries' => 'yes',
